A Pennsylvania Fire Chief felt pressured to resign after using a racial slur to attack the coach of the Pittsburgh Steelers, after the team’s anthem protest last Sunday.

Paul Smith, chief of Muse Township Volunteer Fire Department in Cecil, Pennsylvania, was furious after the Steelers refused to take the field in Chicago during the playing of the national anthem. He was so upset with coach Mike Tomlin that he wrote an angry Facebook post saying, “Tomlin just added himself to the list of no good N*****s. Yes I said it.”

Almost immediately, members of the community began expressing their shock over the comment.

As criticism of his post grew, the chief told the local CBS affiliate that he was embarrassed by his outburst.

“I am embarrassed at this. I want to apologize,” Smith told CBS Pittsburgh. “I was frustrated and angry at the Steelers not standing the anthem. This had nothing to do with my Fire Department. I regret what I said.

“My fire department should have never been dragged into this. It was a bad judgment by me, for which I am very embarrassed, for them and my township,” he added.
